Nguni tribes include the South African Ndebele, whose origins are unknown.
Mzilikazi, a former Zulu general, led the Ndebele to secede from King Shaka in the early 1820s.
Many Ndebele warriors conquered minor chiefdoms and assimilated them into their society.
Zimbabwe's Ndebele population has been declining due to the government's genocide.
Ndebele artists are famed for their painted houses and vivid beading.
Beadwork has long been done by Ndebele women, who are known for their creativity.
Metal rings, beaded hoops, and colourful outfits are employed.
